CROSS-REFERENCE TO RELATED APPLICATION

This application is a continuation of U.S. patent application Ser. No. 16/504,180 filed on Jul. 5, 2019, which claims priority to China Patent Application No. 201811611231.0 filed on Dec. 27, 2018, the entire contents and disclosures of which are incorporated herein by reference in their entirety.

FIELD OF THE DISCLOSURE

The invention relates to the technical field of styling devices, in particular to an angle deflection type twisted hair styling device.

BACKGROUND OF THE DISCLOSURE

A hair styling device, including a hair straightener, a hair curler and the like, is mainly used to design style of hairs. The existing hair straightener generally includes an upper gripping portion and a lower gripping portion, which are openable and closeable through a hinge structure, where an upper clamping head is connected to the upper gripping portion, a lower clamping head is connected to the lower gripping portion, an upper clamping surface is arranged on the upper clamping head, a lower clamping surface is arranged on the lower clamping head, and the upper clamping surface is arranged to be paired with the lower clamping surface and thus an clamping surface for hairs is formed. However, the upper clamping surface and the lower clamping surface are generally flat and straight clamping surface structures.

For example, a Chinese invention patent with authorized announcement No.: CN 206137462 U discloses an angle deflection type hair straightener, which includes an upper clamping plate and a lower clamping plate hinged to the upper clamping plate, where the upper clamping plate has an upper gripping portion and an upper clamping head connected to the upper gripping portion, and the upper clamping head has a twisted deflection angle a with respect to the upper gripping portion, the lower clamping plate has a lower gripping portion cooperating with the upper gripping portion, and the lower gripping portion is connected to a lower clamping head cooperating with the upper clamping head. The angle deflection type hair straightener further includes a printed circuit board (PCB) control plate arranged on the upper clamping plate or the lower clamping plate. When a user uses the hair straightener, the head of the user is better supported and thus can be prevented from being subjected to a lateral pulling force, and a better user experience is obtained. Further, the hair straightener adopts a structure design that is more in line with usage habits, and has advantages of convenient operation and labor saving. Though each of the upper clamping head and the lower clamping head has a twisted deflection angle with respect to a corresponding gripping portion, and thus a convenient user operation is achieved, heat generating plates of the upper clamping head and the lower clamping head are flat and straight, and hair styling effect is not essentially improved.

As another example, a Chinese invention patent with authorized announcement No.: CN 201806120 U discloses a novel electric heating hair iron, which belongs to the technical field of hair treatment devices. The novel electric heating hair iron includes a handle, an electric heater, a clamping arm and a clamping plate. The electric heater is arranged in the clamping arm, and the clamping plate is arranged at an inner side of the clamping arm. A surface of the clamping plate is fixed directly or mounted through a rail on the electric heater. Another surface of the clamping plate is wavy. Two clamping plates arranged on/below the clamping arm are engaged with each other. For the novel electric heating hair iron, compared with a structure of other clamping plate, the structure of the clamping plate of the novel of electric heating hair iron is change from a flat surface or V-shaped surface to a waved curved surface, and thus a variety of hairstyles can be achieved. Further, the clamping arm of the novel electric heating hair iron can adjust its angle, and thus is convenient to use. Though a clamping surface of the clamping plate is changed from a common flat surface or V-shaped surface to a waved curved surface of a same peak height, a styling effect for hairs is too regular, a standard wavy shape hairstyle makes hairs lack of layering, and it is required to constantly switch an angle of the electric heating iron, when the user wants to change a hairstyle, thereby causing a large hand movement and an inconvenient operation.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The invention will be further described in detail below in conjunction with accompanying drawings.

Disclosed is an angle deflection type twisted hair styling device, including an upper gripping portion and a lower gripping portion openable and closeable through a hinge structure. An upper clamping head is connected to the upper gripping portion. A lower clamping head is connected to the lower gripping portion. An upper clamping surface is provided on the upper clamping head. A lower clamping surface is provided on the lower clamping head. The upper clamping surface has an upper twisted deflection angle with respect to the upper gripping portion. The lower clamping surface has a lower twisted deflection angle with respect to the lower gripping portion. The upper twisted deflection angle equal to the lower twisted deflection angle. A hairstyle with an inclined angle and a twisted shape can be realized without rotation of a user's hand, and the hairstyle can be completed without major changes to perm action.

As shown in FIG. 1 , an embodiment of the invention provides an angle deflection type twisted hair styling device including an upper gripping portion 1 and a lower gripping portion 2. The upper gripping portion 1 and the lower gripping portion 2 are openable and closable through a hinge structure. An upper clamping head 3 is connected to the upper gripping portion 1, a lower clamping head 4 is connected to the lower gripping portion 2, an upper clamping surface 5 is provided on the upper clamping head 3, a lower clamping surface 6 is provided on the lower clamping head 4, and the upper clamping surface 5 is arranged to be paired with the lower clamping surface 6. The upper clamping surface 5 has an upper twisted deflection angle 10 with respect to the upper gripping portion 1, and the lower clamping surface 6 has a lower twisted deflection angle 11 with respect to the lower gripping portion 2. The upper twisted deflection angle 10 is equal to the lower twisted deflection angle 11, such that a fitting between the upper clamping surface 5 and the lower clamping surface 6 is ensured. Both the upper clamping surface 5 and the lower clamping surface 6 are electrically connected to an electric control device, so as to achieve electric heating. In order to ensure heat generation efficiency, the upper clamping surface 5 is a heating surface of an upper heat generating plate, and the lower clamping surface 6 is a heating surface of a lower heat generating plate. That is, the upper heat generating plate has the upper twisted deflection angle with respect to the upper gripping portion 1, and the lower heat generating plate has the lower twisted deflection angle with respect to the lower gripping portion 2.

Furthermore, the upper clamping head 3 has the upper twisted deflection angle with respect to the upper gripping portion 1, and the lower clamping head 4 has the lower twisted deflection angle with respect to the lower gripping portion 2. Since each of the upper clamping head 3 and the lower clamping head 4 is provided with a corresponding twisted deflection angle, the user's operation is more convenient and labor-saving.

As shown in FIGS. 2-3 , the upper twisted deflection angle and the lower twisted deflection angle each are in a range of 60-120 degrees. The upper and lower twisted deflection angles each use an inner side plane of the corresponding gripping portion and a plane where an end of the corresponding gripping surface (an outer end) as reference bases, and an axis about which each of the upper clamping head and the lower clamping head is twisted is a long axis of the corresponding gripping portion. That is, regarding the upper clamping surface, the upper clamping head and the upper gripping portion, twisted axes therefor are all on a same axis, and in the illustrated embodiment the long axis of the upper gripping portion is used as the same axis. Regarding the lower clamping surface, the lower clamping head and the lower gripping portion, twisted axes therefor are all on a same axis, and in the illustrated embodiment the long axis of the lower gripping portion is used as the same axis.

Furthermore, an upper heat insulating layer is arranged between the upper clamping head 3 and the upper clamping surface 5, and a lower heat insulating layer is arranged between the lower clamping head 4 and the lower clamping surface 6. The upper heat insulation layer and the lower heat insulation layer respectively prevent heat of the heat generating plates from delivering to the upper clamping head 3 and the lower clamping head 4, such that a temperature difference is formed between the upper clamping head 3 and the upper clamping surface 5, and also formed between the lower clamping head 4 and the lower clamping surface 6. The upper heat insulation layer and lower heat insulation layer may be made of a cold gel or heat insulation foam.

As shown in FIG. 4 , in another embodiment, an outer edge of the upper clamping surface 5 is provided with upper side teeth 8, and an outer edge of the lower clamping surface 6 is provided with lower side teeth 9. When hairs are clamped between the upper clamping surface 5 and the lower clamping surface 6, the upper side teeth 8 and the lower side teeth 9 may be engaged/meshed with each other or may not be engaged with each other, and can be used to comb hairs. Furthermore, the upper side teeth 8 and the lower side teeth 9 can be provided in one turn, two turns, and the like.

An auxiliary gripping portion 7 is provided at an end of the upper clamping head 3 or an end of the lower clamping head 4. When the angle deflection type twisted hair styling device of the invention is used, the upper gripping portion 1 or the lower gripping portion 2 is gripped by one hand, and the other hand assists in gripping the auxiliary gripping portion 7, thereby enhancing gripping effect of hairs.

A working principle of the angle deflection type twisted hair styling device of the invention is as follows: holding the upper gripping portion 1 and the lower gripping portion 2 by hand, opening the upper clamping head 3 and the lower clamping head 4 so as to put hairs in a clamping region defined between the upper clamping surface 5 and the lower clamping surface 6, and starting a power supply of the hair styling device (can be also pre-activated), the upper clamping surface 5 and the lower clamping surface 6 will be heated, the upper clamping surface 5 and the lower clamping surface 6 then are closed, a hairstyle with a twisted shape can be completed by using the hair styling device to pull hairs straightly.
